Have you ever seen your child cover their ears at the sound of a vacuum, or melt down at the feeling of a clothing tag? These may be signs of sensory processing difficulties — and if your child is also on the autism spectrum, you’re not alone.
Sensory Processing Disorder (SPD) is not an official DSM-5 diagnosis, but it is widely recognized by occupational therapists and educators as a real and impactful condition. Research shows that over 90% of children with autism experience sensory processing challenges.
This article explains what SPD is, how it shows up in autistic children, and how families can help.
What Is Sensory Processing Disorder (SPD)?
SPD refers to difficulties with the way the brain receives, organizes, and responds to sensory input. This input may come from the five traditional senses — sight, hearing, touch, taste, and smell — plus two lesser-known senses:
-
Proprioception (body awareness)
-
Vestibular (balance and movement)
Children with SPD may be hypersensitive (overreactive), hyposensitive (underreactive), or a mix of both depending on the situation.

Sensory Processing and Autism: The Connection
Sensory issues are a core feature of autism under the DSM-5. Autistic children may:
- Cover their ears in response to everyday sounds
- Avoid certain textures or clothing
- Seek sensory input through spinning, flapping, or chewing
- Become overwhelmed in busy or loud environments
These are not “bad behaviors” — they are coping strategies for a world that can feel too much or too little.
How SPD Looks in Real Life
Sensory difficulties can affect nearly every part of daily life:
-
Getting dressed: discomfort from tags, seams, or fabric textures
-
Eating: sensitivity to food textures, smells, or temperatures
-
Bathing or brushing teeth: challenges with water pressure, noise, or taste of toothpaste
-
Transitions: reacting to bells, alarms, or crowded hallways
-
Social play: struggles with noisy, unpredictable environments
Sometimes what looks like a tantrum is actually sensory overload. Recognizing this helps parents respond with empathy rather than discipline.

How to Help a Child with SPD and Autism
Supporting your child starts with understanding their sensory profile. Here are practical strategies:
- Create a sensory profile: Track what triggers and soothes your child.
- Work with an occupational therapist (OT): Look for one trained in sensory integration.
- Use sensory tools: Noise-canceling headphones, chewy necklaces, weighted blankets.
- Prepare your child for transitions: Use visual schedules and countdowns.
- Adapt the environment: Reduce noise, soften lighting, or build in movement breaks.

When to Seek Support
If sensory responses disrupt daily life, interfere with learning, or cause significant distress, consider a sensory evaluation. Occupational therapy (OT) can be life-changing, and children may qualify for school supports like an IEP or a 504 Plan.
Early intervention often leads to better outcomes, but support at any age can help children thrive.
Final Thoughts
Children with autism often experience the world through a heightened or altered sensory lens. Viewing their behaviors as communication instead of defiance can shift the way you respond.
By tuning in and adapting environments, you can help your child feel safe, regulated, and more connected to the world around them.
